Hi,

I am very new to Stateflow, and I have created a simple state machine on Matlab 2012b (32-bit version). Whenever I try to an Update Diagram or start the simulation, I get the following model error message:

"Undefined variable "emlcoderprivate" or class "emlcoderprivate.compiler_supports_eml_ipp".

I have tried using Microsoft Visual C++ 2010 Express as the compiler, but I still get the same error message.

Can anyone please help me shed some light into this?

Thank you so much for all of your help, Victoria

what do you mean by saying"Now when you re-open Matlab, you might get an error if the default directory is set to Windows. You can change that by right-clicking on the Matlab icon -> select "Properties" -> specify any path other than Windows in the field "Start in". ”
